Liquid crystal elastomer micro-structures and their applications
Liquid crystal elastomers(LCEs)have potential applications in medical micro-robotics,controllable surface microstructures,and microfluidics due to their programmable shape morphing and up to 400%strain.To achieve high-resolution molecular orientations and high-precision LCE microstructures,advanced alignment and micro/nano-fabrication techniques are required.Here,we presented current alignment techniques and micro/nano-fabrication techniques for LCE micro-structures,summarized their applications in micro-actuators,artificial muscle fibers,and controllable surfaces,and envisaged their future development in medical micro-robotics.
